* Change SPU register re-interpretations from OR to COPY_TO_REGCLASS instruction.Kalle Raiskila2010-09-16
| | | | | | | | | | | | | | This cleans up after the mess r108567 left in the CellSPU backend. ORCvt-instruction were used to reinterpret registers, and the ORs were then removed by isMoveInstr(). This patch now removes 350 instrucions of format: or $3, $3, $3 (from the 52 testcases in CodeGen/CellSPU). One case of a nonexistant or is checked for. Some moves of the form 'ori $., $., 0' and 'ai $., $., 0' still remain. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114074 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a InitSections method to the streamer interface.Rafael Espindola2010-09-15
| | | | | | | | | | | | | | The ELF implementation now creates text, data and bss to match the gnu as behavior. The text streamer still has the old MachO specific behavior since the testsuite checks that it will error when a directive is given before a setting the current section for example. A nice benefit is that -n is not required anymore when producing ELF files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114027 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | "The register specified for a dregpair is the corresponding Q register, so to get the pair, we need to look up the sub-regs based on the qreg. Create a lookup function since we don't have access to TargetRegisterInfo here to be able to use getSubReg(ARM::dsub_[01])." Additionaly, fix the NEON VLD1* and VST1* instruction patterns not to use the dregpair modifier for the 2xdreg versions. Explicitly specifying the two registers as operands is more correct and more consistent with the other instruction patterns. This enables further cleanup of special case code in the disassembler as a nice side-effect. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113903 91177308-0d34-0410-b5e6-96231b3b80d8
